I'm getting some odd behaviour from my Grid field in the template (unless I'm misunderstanding the Grid docs). I have a custom Grid field used for placing images (columns are file, alt text and caption). In one of my channel entries I have three images set via this field. The following template code displays all three images, as expected:

{my_image_grid}
<figure>
    <img src="{my_image_grid:file}" alt="{my_image_grid:alt}">
    <figcaption>{my_image_grid:caption}</figcaption>
</figure>
{/my_image_grid}

And, also as expected, this code displays only the contents of the first row of the grid field:

{my_image_grid row_id="1"}
    <figure>
        <img src="{my_image_grid:file}" alt="{my_image_grid:alt}">
        <figcaption>{my_image_grid:caption}</figcaption>
    </figure>
{/my_image_grid}

However, when I try to display all rows other than row 1, with the following:

{my_image_grid row_id="not 1"}
    <figure>
        <img src="{my_image_grid:file}" alt="{my_image_grid:alt}">
        <figcaption>{my_image_grid:caption}</figcaption>
    </figure>
{/my_image_grid}

I get just the first row again. Just the first row is also displayed if I try to display a specific row other than 1:

{my_image_grid row_id="3"}
    <figure>
        <img src="{my_image_grid:file}" alt="{my_image_grid:alt}">
        <figcaption>{my_image_grid:caption}</figcaption>
    </figure>
{/my_image_grid}

Can anyone else verify this behaviour before I report it as a bug? Or am I doing something wrong (eg. misunderstanding how rows are ID-ed)? This is EE 2.7.2.

Thanks.

It seems row_id works on the database table ID, not on the row number.
Use the offset parameter and {gridfield:count} variable instead.

 

In my opinion it's a bug, because if you only provide one row, the grid-parser will not take "not" into account somehow. To circumvent this bug add a zero in front so that it 'thinks' it has multiple entries. ``` row_id="not 0|1" ```

(ps. bug filed: https://support.ellislab.com/bugs/detail/19852 )

  • Hmm. Adding the zero as you suggest seems to bypass the row_id parameter entirely, because now I'm getting all three rows again, not just rows 2 and 3 as I should. It definitely appears to be a bug, but it goes farther than just the 'not' part of the parameter, as demonstrated by the fact that row_id="3" doesn't work either (see the last code example in my original post). I'll add a comment to your bug report, GDmac, with some extra info from my own experiences.

  • i tested with row_id="3" and row_id="not 0|3" and all works. But if you do row_id="4", and only have 3 rows, it will show row 1. (adding to bug report)

  • I've editted the post, row_id is database related, not row number related.

  • Thanks for that. I think in that case that the database table ID should be easier to find -- it's pretty elusive as things stand.

  • you can use {if gridfield:count == 2 || gridfield:count == 3} or check if greater than {if gridfield:count > 2}
